Application filed May 8, 1906. Serial No. 315,719-

To all whom it may concern:

Be it known that I, EDWARD I. TENNANT, a citizen of the United States,residing at S ringeld, in the county of Clark and State 5 0 Ohio, haveinvented certain new and useful Improvements in Pneumatic-TireProtectors; and I do declare the following to be a,

full, clear, and exact-description of the invention, suchy as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying'drawings, and to theletters and vfigures of reference marked thereo'n, which form a particithis specification.

This invention relates to new and useful improvements in pneumatic-tireprotectors. he object of the invention is to provide means whereby apneumatic tire is rendered puncture-proof and the life of the tire isgreatly augmented.

It also provides means whereby skidding is prevented toa great extent. oOne of the advantages I claim for my invention is that the protectoronly covers the ltread of the4 tire, the sides being left exposed,thereby preventing the tire from heating, which is very detrimental tothe rubber.

Referring to the drawings, Figure 1 is a side elevation of an automobilewheel equipped with my new pneumatic-tire protector. Fig. 2 is a sectionon the line x of Fi 1-. Fig. 3 is a detail of the turnbuckleho dingmechanism. Fig. 4 is a detail showing the construction of the flexibleloops. Fig. 5 is a sectional detail of one of the metallic plates placedon the periphery of the tireprotector.

Throughout the specification similar refer-V ence characters indicatecorresponding parts. Referring to the drawings, 1 represents a rim of awheel, upon which 1s mounted in any suitable manner a pneumatic tire 2.Extending around the outer surface of said tire is an endless band ofelastic material 3. This elastic material may be made of leather,rubber, or cloth. Extending around the tire above said band 3 is anendless band 15, which is placed in a zigzag-line, as shown in Fi' 4. Aswill be seen from the drawings, this band forms loops 8 on each side of`the band 3. The object ofthese loops will be hereinafter described.Extending above the band 15 is a band 5, similar to the band 3. Thesebands 3, 5, and 15 are of the desired thickness to impart the necessarystrength.

The intervening space between the bands 3v and 5, which is formed by theband 15 crossing said bands, is filled in with strips of suitablematerial 4, which are of the-shape shown l in Fig. 4. The ends of thepieces 4 are cut on a taper to match the sides of the endless band 1 5,which is laced over the elastic band 3. The said pieces 4 are thenplaced in position to fill the spaces between the band 15 in crossing.

Mounted on the outer band 5are a suitable number of metallic plates 6,which are held in place by rivets 7. These plates are so shaped thatthey will cause any object they may strike to glance off. These rivets 7extend through the bands 3, 5, and 15 and the strips 4 and serve to holdthe said bands rigidly together. The plates 6, each having at one edgean upturned portion 14, produce a roughened surface on the face of thetireprotector, and thereby prevent skidding,

-which is very detrimental to pneumatic tires on automobiles and isespecially valuable in case of ice. The direction in which the wheelrotates is shown by the arrow in Fig. 1,\and it will be seen that itWill be impossible for the upturned edges' 14- to gather mud. When theprotector is placed on the tire, the loops 8, formed by the bands l5,lie flat against each side of the tire. A ring 9 is passed through saidloops 8 and is tightened by turnbuckles 10. To prevent the turnbuolgles10 from unloosening, I provide a sleeve 11, having a loop 12 thereon.This sleeve is passed over the turnbuckle after it is suflicientlytightened. A strap. 13 is then passed through the loop 12 and alsothrough a similar loop on the opposite side ofthe tire. It will be seenthat by this means it will be impossible for the turnbuckles to becomeun loosened.

I claim 1. In a tire-protector, a tire, an velastic tread-b andinclosing the tread ortion of said tire, a band of fabric materiacrossing said elastic tread-band and forming loops on ea'ch side of thetire, a series of strips of fabric covering the elastic band at pointsbetween the cross-band and filling the spaces between the cross-band,rings passing through the loops formed by the cross-band, and means fborcontracting said rings to tighten the cross- 2.
